18Lab2 Track Automation

[Syllabus] [Overview]

Overview

Logic distinguishes between two types of automation: Region and Track. Region based automation applies to a single region and was covered in 18Lab1 using Hyper Editor and Hyper Draw. Track based automation applies to all regions in a single track and can be recorded by moving knobs and sliders as you're listening. Logic uses internal "meta messages" to record values in the Mixer, software instruments, and effects plug-ins.

Keep regions 1-3 and delete the others. Region 2 has the Volume automation and region 3 has the Pan automation.

You can tell Automation has been enabled by the white border around the Automation button and by the gray appearance of the track lane.

Set Automation to Touch.

Touch Automation

Logic will record any Volume fader movements while the song is playing. You do not have to turn on the Record button.

Touch automation

Move the playhead to where you want to start recording. Drag the Volume Fader to the level you want to begin with. Press the space bar, or click the Play button, and as soon as possible click, hold, and drag the Volume fader up and down while the song is playing. You should see the automation appear as you're recording.

Release the mouse button when you're done recording. Press the space bar to stop playing.

Play

Set the Automation type back to Read, either in the Mixer or in the Track area to prevent you from accidentally recording automation as you listen.

A third way of recording Automation is to use the small vertical slider in the track header of the Arrange window. Set the Automation menu to display Pan. Enable touch. Move the slider as you record Pan. Region 2 should still be selected.

After you're done recording Pan automation, enable Read automation, play and listen.

Copy and Paste Automation

You've just decided you'd rather have the Pan automation in Region 3.

Open the Lists Area

If you could see the automation events in the Lists area it would be simple to cut and paste from Region 2 into Region 3. However, automation does not appear in the Lists area. The solution is to convert the Track automation back into Region automation.

Select Region 2 and use the Track mini menu choose the "Move Visible Track Automation to Region" item because you only want to move the Pan automation without affecting the Volume automation.

Convert Track Automation to Region Information

After choosing this menu item, Pan automation will be removed from the track area and Pan control messages should appear in the Lists area.

Select all Pan Control data and Cut (Apple-X).

The Pan automation that was in Region 2 is now in Region 3. Manually edit the entry and exit points to Pan center.

Play

Turn the Automation button back to Read and play.

HyperDraw Automation (18Lab1) vs. Track Automation (18Lab2)

HyperDraw automation works only on MIDI tracks. It uses the same MIDI controller messages (status Bn) you learned about earlier.

Track Automation works on both audio and MIDI tracks. It uses specific LogicPro defined meta-events to record the fader movements.

HyperDraw is best used for track based expression.

Track Automation is best used in the final mix to balance parts.
